This invention relates to mountings for use in connection with eyeglass lenses -'for supporting'the nose bridges and ear Cloops or other types and kinds of attachments 'to glasses; and `the `object ofthe invention is 'to provide amounting "of `the class described having aspringtong-like *engagement with 'the lperipheral edges of 'the flens and particularly lwhere 'comparatively 'thick lenses are `employed so that the lens 'may' be quickly and `easily 'attached 'and detached 'with Y' respect to the mounting, 'and eliminating the Ause 'of cement, screws, rivets, and kother fastening devices, such `as'are commonly employed; a

further-objectbeing to provide tong-like frames for `mounti'ngs ofthe character ldescribed where- `in the terminal ends thereof include lens engag- 'ing projections Iwhich extend 4lonfgitudinally 'of Vor Aare spaced longitudinally of the periphery'of 'the lens to `support therlens against tiltingmoveyment in the'framesand further rtotheprovision f of means reinforcing'and concealing 'that "part -parts of my improvement are designated by suitable reference characters in feach 'of the views; and in which:

Fig. 7 represents a transverse sectionall view which might be taken through any one lof the structures as seen in Figs. 4, A5, and I6 when in assembled position and showing another adaptation of the invention.

To diagrammatically illustrate one of 'many' l"types 'and 'kinds o`f r`eyeglass structures, Ihave indicated in Fig. 1 of the drawing 'a'pair Aof 'glasses lcomprising two lenses I0 and "I I, la nose 'bridge I2 and ear loops 1'3. In the construc- "tion shown vouter-side edges I4 and inner side edges 'l5 of both lenses 'have longitudinally spaced sockets I6 as most clearly illustrated vvin :Figm4 of the drawing. These sockets are ar- I'ranged atfdiierentverticallevels on the periph- 'ery ofithe lens to provide what might betermed the'high 'mounting of the ear "loops Ain connection 4 with the 4conventional nose mounting or bridge At `I'l are showntwo identical 'lens supporting drames; `and A`as these frames are of the same construction, the brief description of one will ap- *ply to the other. Each frameA comprises a loopshaped rod or strip f8,v which is shapedto conform with 'the peripheral contour of 'the lens and is preferably located at the periphery of the lens in the manner illustrated so as to'become substantially invisible when viewing the lenses from ithe front of the eyeglasses or spectacles. 'The rods ior strips. f8 are of spring construction.

""Ihe downwardly vextending ends lof the strips t8,

namely I9 and 20, the end I9 being termed the inner-end;4 and the end 20 the outer end for purposes of description, have offset portions 2| extending in the direction of the periphery of thelens. Theseportions also extend outwardly and upwardly "to form terminal clip ends 22 which are `of substantially L-shaped cross lsectional form. As will appear upon a consideration of Fig. 3 of the drawing, the` part 42 3 of these ends rests upon the periphery of the lens, where- "as the part 24 rests upon the outer surface of the lens to reinforce the lens and `also to cover the recesses or apertures I6 formed therein.

move the terniinalends 22v toward each other and in `mounting the lens in vthe frame, the terminal ends are separated -by placing'one side edge, for example the edge I5 of thelens in'its associated `coupling 22, and then springing the outer coupling '22 over the outer peripheral edge I4. vIn fd'etaching the lens the outer coupling' y22 is -rs'tmoved out of engagement with the sockets I6 Aand the edge I4 as will be apparent.

It will, of course, be apparent that-any type `of nose 'bridge construction may be employed;

and this bridge may be attached to the terminal ends 22 in any desired manner. It will also appear that when ear loops are employed, such as the loops I3, the forward ends 26 of these loops may have any desired mounting in connection with the couplings 22. In the construction shown, the ends 26 are illustrated as pivoted between bearings 21 arranged upon outer terminal ends or couplings 22., v Y

In Fig.` of the drawing is Y shown a slight modification of the construction shown in Figs. 1 to 4 inclusivawherein an arc-shaped recess 28 is substituted for the two recesses I6; and an elongated arc-shaped projection 29 is providedon This the couplings 30 to enter the recess 28. type of construction will forma sufficient key action to retain the lens against tilting actionin the mounting frame. frame will also include cover plates 3|, similar to the plates 24.

' f In Fig. 6 of thedrawing is shown another adaptation of the invention wherein an elongated recess 32 is provided in the periphery of the lens, and an elongated key rib or member'33 is provided on the terminal or coupling end 34, the

reinforcing and cover plate 35 also being employed.

- In Fig. 'I of the drawing I'haVe illustrated that it is not essential that the recesses in the lens be disposed intermediate inner and outer surfacesof the lens; and where thinner lenses are employed, the recesses of the type and kind illustrated in Figs. 4, 5, and 6 may be disposed on either side surface 0f the lens, but preferably on the inner surface. In Fig. '7, the recess in the lens is shown at 36 opening through the inner surface 31 of the lens. and the coupling or terminal end .38 of the frame is provided with a projection or projections 39 forfentering the recessed portion -of the lens as at 36. In other words, the recesses 36 may take the place of the'recesses I6, 28, 32;

and the projection 39 may take'the place of the projections 25, 29 and 33, as-shown in Figs. 4, 5, and 6 of the drawing. The terminal end 38 of the frame also includes the `cover and reinforcing plateM), and in all instances-it will appear that this plate in addition to covering the coupling or recessed portion of the'lens also servesto reinforce that part of the lens in connection with which the couplings are mounted.

- justment of the U-frame with respect to the rear Surface -of the lens, either byplacing a tool between the parts 2|, 23 and separating said parts, or by pinching Athe parts together. by a pair of pliers. In this connection. itv will be apparent that the U-frame may be disposed upon the inner surface of the lens, or this frame may be slightly spaced therefrom.v f v It will be understood that whenusing key or coupling elements of the type andkind illustrated in Figs. 5 and 6 on the terminal ends of the tonglike frame members, these elements may be made very thin to lt in narrowslots formed in the peripheral edge of the lens,thus adapting the `device to lenses of thin construction. It would appear that my present construction of snap-,on

mountingv framefor lenses maybe applied :to lenses without altering the sizes of moreor` less standardized lens structures; that is to say, where -lenses are pre-made to a given dimension, these The terminal ends of the lenses may simply be shaped to form the key sockets for receiving the key elements of the mounting frame.
